Interacoustics VRA201 Gebrauchsanweisung Seite 23

Note 1 At 80 MHz and 800 MHz, the higher frequency range applies
Note 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the VRA201 is used exceeds the applicable RF compliance level above, the VRA201 should be observed
to verify normal operation, If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the VRA201.
b) Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
